b, F, and G denote plus the semantic rules for determining complex truth
conditions from simpler ones.
Suppose we could do the same for English, that is, construct a truth defini-
tion that spits out something of the form, "`----' is true if and only if ----"
for each English sentence. (Such products are called "Tarski biconditionals" or
"T-sentences," since they were inspired by the form of Tarski's (1956) theory

truth condition right. Then, Davidson asks, what more could reasonably be
asked of a theory of meaning for English?
Consider: A correct assignment of meaning to a sentence should determine
that sentence's truth condition; so we know that an adequate theory of mean-
